T0 ALL-WHOM IT MAY CONGERN:

Be it known that I, WnssEL BRODHEAD, of the city vofu'lMeadville, in the county of Crawford, and State of Pennsylvania, have invented an improved Mode'of-Making Joiners Gauges, and fastening the same without the aid. of wedge or screw, consisting of two pieces and -a marker. r

I make my gauges of the ordinary sizes in use.

The bar is made oval, elliptical, or cam-shaped, to slide in a corresponding hole in the head-piece, so that,- by a. slight twist of the bar in one direction, and the head-piece in the other, they are rmly xed to each other at any point on the bar.

Figure 1 shows an oval or elliptical-shaped bar, A, fixed in a. corresponding hole in the head-piecel B. v

Figures 2 and 3 show a cam or scroll-shaped bar in its corresponding hole; C C being.the marker; the dotted and full lines showing about the distance the parts move upon each other inthe act of tightening.

I construct my bars from long pieces, planedout with a` proper tool, and afterward cut to the proper lengths. The head-pieces are first bored, and then, witha gouge tocorresponrl with the form of the bars, fitted in a mortising-machine. With one stroke the hole is completed.

What I- claim as my invention, anddesire to secure by Letters Patent, isl -The bar A and the head-piece B, constructed and operated as and for the purpose set forth.
